A practical origin
Static images could leave persistent marks on CRT displays. Screensavers changed or removed that image. The historical purpose should not be treated as a universal recommendation for every modern display.
Personal expression
Moving shapes and messages became a way to customise an otherwise practical workspace. Microsoft’s account of the 3D Pipes screensaver records the creative decisions behind one familiar example.
Separate functions
Animation, session locking and energy management are different things. A moving picture does not necessarily save power, and a screensaver is not automatically an access-control mechanism.
Remembering the pauses
Version, display proportions and execution speed help reconstruct an old experience. Screensavers are historically interesting because they document the moments between productive tasks. They gave machines a recognisable visual personality and became part of how people remember their homes and workplaces.
